At Old Sac’s north end is this impressive collection of railcars and locomotives from miniature to true scale. While the candy-coated recounting of the struggles of those who laid the track is unsettling, the fully outfitted Pullman sleeper and vintage diner cars will thrill rail fans. Board a restored passenger train (adult/child $10/5) from the Sacramento Southern Railroad ticket office, across the plaza on Front St, for a 40-minute jaunt along the river. Train rides run hourly on weekends from April to September.
